To all 'whom it may concern Be it kiiown'tliiit l, (leonor: Y. PARLIER,a eitizen ofv the` lliiited States, residing at Uurrolltoi'i, iii" thecounty of Carroll and State of (l'eor ia, have invented a new and usefulStove-l amper, of which the following is a specification.

This inventionl relates to stove dempers, and aimsl to provide a noveland improved damperstructure, which is readily operable for swinging andholding the damper, nnd which is unique, yet simple and convenient inconstruction. 0

With the foregoing and other objects 1n view which will appear as thedescription proceeds, thc invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings accompanying this specification and forming a partthereof, the referred embodiment of my invention is i iistrated, inwhich Figure 1 is a longitudinal sectional View of a stove havingseveral of the improved dan'ipers. Fig. .2 is a transverse sectionalview thereof taken on the line 2 2 of Fig. l. l `i 3 is iin enlargedfragmental view in section taken on theiue 3-3 of Fig. 2.

Referring to the drawings, iii which siini lar reference numeralsdesignate corresponding parts throughout the several views. the numeral4 indicates the stove easpipe 6 coming inciosiiig the oven iuunieuteswith the tlue between the casing und oven. 'lhc upper left hand cornerof the oven is provided with the fire box T therein, and below which issituated the ash it 8, the two being divided by the rate 9. ll`he ashpit does not extend to the ottoni of the oven so that thc portion 10 ofthe oven chamber is situated directly below the ash pit to be directlyheated thereby. The water back 11 communicates with the water tank 12 bythe pi es 13 and thus provides for the supply ofphot water in a mannersimilar to the ordinary stove. Dampers 14 and l5l are positioned at thetop of the oven adjacent the sides of the fire box and swing through thearcs as indicated in dotted lilies. The damper 14 is adapted to swinginto the position indicated in dotted lines in Fig. l. and when sopositioned will cut the fire box oil' from direct communication with the(lue and force the products of combustion through the spaces 16, 17, 18and 1S), around the oven so that the oven will be uniformlv heated. 'lhedamper 15 is used to control the area of discharge outlet for the gases.

At times it is essential that the oven be more highly heated at the topthan at the. bottom and for this reason a third damper 20 has beenprovided and is located at they upper corner of the oven remote fromthe. demper 14. With the damper 2O closed as indicated in the drawingand the damper l5 open, the liot gases will circulate freelyv above theoven but will be prevented from entering either to the sides or belowthe same.

Each of the duinpers 1l, 15 und 2O coniprises a damper rod 22 journaledwithin the casing and having one end portion protruding therefromthrough an aperture or bea-i'- iiig 29. provided 'in the front side ofthe casing. r[The damper plate or wing Q3 is secured upon and carried bythe rod 29, and a tubular member 26 is slidable upon the protrudingrportion of the rod 22 and is coiistrainet against rotation thereon.(omplenieiiting handle sections 21 and 27 are secured to the protrudinfend of the damper rod und thel outer en of the tubular member,respectively, the handle seetions bein semi-spherical and forming nhollow divided handle. .1 coiled wire expansion spring `28 is disposedupon the damper rod 22 between the sections of the handle. to be housedwithin the handle, and for yicldably forcing the tubular incinA bei' 9Ginward or toward the stove casing. The handle section 24 of the damperrod is preferably secured and held in place thereon by means of a nut 25threaded upon the end of the damper rod. The inner cnil of the tubularmember '26 and stove casing are rovided with intel-engaging means forholding the tubular member at various angular positions to which it isswung, tx) thereby hold thc damper at the desired position. Thus, theinner end of the tubular member 26 is provided with a pair of oppositecurved fingers 29 engagcuble in opposite arcuate series of notches 30provided in the 'outer 'sideioffthe stove casing. The inner 'end f thetiihular tneinber 26 is also provided with a radial ointer 31coperating,` with'the raduatec `eea-le 32 upon the casing for in icatingthe position of the damper. When it is desired to swing vthe damper, thehandle 24"27 is grasped in the hand and the `handlesections'are drawntogether, against the tensionof the ,spring 28. which will result inthe"ti'ibularmember' .26 being slid ont-ward to disenga e the fingers 29'nfrtiin the n'otehes 30' an whereby the handlenn'iy befr'eadily turnedto 'swing the damper' as, dslrp'ldr lWhenfthe handle is released,` thetubulau'ineniber 26 will be slid inwardly'fuiidei" the influence of thesprin" 28,'to again' 'en a re the tin ers 21) with the notches B0 forioI ding the amper in' la'ce'.'v

he dii'm )er actuating mechanism is convenient an eflicient inconstruction and operat-ion,` and enables the damper to 'be readilyadjusted and 'held at various adjusted positions.

lliirinnr thus fully described in invention, what I cain as new is:-

ln adnmper structure, a easing haring a damper rod journaled therein andlhaving one end portion-pmtruding therefrom,

a damper carried by the said rod with the "eu'singy a tubulin' memberslidable upon the protruding,r portion of the rod and constrained'against rotation thereon` the inner end of the tuhiiliii ineii'ilier andthe casing 'having 'interengagealile means, complementing handlesections secured to the outer end of the tubular iiiember and to theprotruding end o i' the damper rod`r respectively, the s aid handlesections forming a hollow divided y hainlle, and an expansion spring C.K.
